當混凝土攪拌機設備出現粉料進料緩慢的故障現象:螺旋輸送機送料很慢,送料時間超過2分鐘,在正常送料情況下20秒之內就可以輸送完畢。
When the concrete mixer equipment has the problem of slow feeding of powder: the screw conveyor is slow in feeding, the feeding time is more than 2 minutes, and the conveying can be completed within 20 seconds under the normal feeding condition.
而造成這種故障出現的原因經過分析:
The causes of this kind of failure are analyzed
影響因素主要是粉料罐下料不暢和螺旋輸送機損壞等。粉料下料不暢的表現形式有粉料起拱、粉料罐口出料口處物料結塊、出料蝶閥開度過小、粉料罐內物料不足等。螺旋輸送機損壞主要是螺旋葉片變形,不能正常輸送。
The main influencing factors are the unsmooth discharging of powder tank and the damage of screw conveyor. The forms of unsmooth cutting of powder include powder arching, material caking at the outlet of powder tank, too small opening of discharge butterfly valve, insufficient material in powder tank, etc. The damage of the screw conveyor is mainly the deformation of the screw blade, which can not be transported normally.
處理過程:
Process:
1.開啟氣錘破拱裝置。
1. Open the air hammer arch breaking device.
2.檢查粉料罐卸料蝶閥的開度,并使蝶閥處于全開的位置。
2. Check the opening of the discharge butterfly valve of the powder tank, and make the butterfly valve in the fully open position.
3.檢查粉料罐出口處物料是否結塊。
3. Check whether the materials at the outlet of powder tank are caked.
4.檢查螺旋機葉片是否變形,如變形則拆除校正或更換。
4. Check whether the blade of screw machine is deformed. If it is deformed, remove it for correction or replacement.
